This female great white was 6.1 m (20 ft) long. However, there was a report considered reliable by some experts in the past, of a larger great white shark specimen from Cuba in 1945. This specimen was 6.4 m (21 ft) long and had a body mass estimated at 3,324 kg (7,328 lb).
ALS (amyotrophic lateral sclerosis), also known as Lou Gehrigs disease, is a progressive disease of the motor neurons (nerve cells that control the skeletal muscles). As motor neurons are affected, gradual weakness, atrophy, and paralysis of the skeletal muscles occur.
Amyotrophic lateral sclerosis. Overview. Amyotrophic lateral sclerosis (a-my-o-TROE-fik LAT-ur-ul skluh-ROE-sis), or ALS, is a progressive nervous system (neurological) disease that destroys nerve cells and causes disability. ALS is often called Lou Gehrig's disease, after the famous baseball player who was diagnosed with it. ALS is a type of motor neuron disease in which nerve cells gradually break down and die. Doctors usually don't know why ALS occurs. Some cases are inherited.
